    G Series

    Based on our late model large case GM housings, the tried-and-true G series of alternators are our best sellers. Reasonably priced, these units feature solid copper custom rectifiers with huge 65 amp diodes for great durability. Premium OEM quality bearings ensure long life even in hot or abusive conditions.

    Installation Notes:

    This unit comes equipped with a smaller 1.75 inch diamter alternator pulley, and will require a slightly shorter drive belt for proper belt tension. Not recommended for use above 5,000 RPM engine speed.
